The latest forecast from the National Weather Service office in San Diego predicts heavy rain in region starting Wednesday night.
“Light showers possible as early as Tuesday as a strong atmospheric river begins to take shape along the coast,” the weather service said. “The main rain event is anticipated Wednesday night into Thursday, with flash flooding and debris flows near recent burn scars possible.”
Rainfall is expected to range from .5 to 1 inch in the San Diego city limits, up to 1.5 inches in the coastal valleys, and 2 inches or more in the mountains. The snow level will be high, however — above 9,000 feet.
Farther north, the Los Angeles area is expected to get even more rain, with up to 4 inches forecast in the city limits.
The weather service said the atmospheric river is currently taking shape over the east central Pacific.
